Asked by Alex I.

So i am having a hard time with special right triangles and wanted to know how to solve problems such as: (45,45,90) and (30,30,60) problem. I know how to do it but need extra help.

are your 3 numbers in the bracket supposed to be angles?
if so then the first is an isosceles right-angled triangle, with sides in the ration of 1 : 1 : √2

the second one can't be triangle, since the sum of the 3 angles does not add up to 180
Was it supposed to be 30, 60, 90 ?
If so, then it is a right-angled triangle with sides in the ratio 1 : √3 : 2
